You may recognize ingredients like sugar, cocoa butter, and milk powder when you look at an M&M pack. Gum arabic, carnauba wax, dextrin, and food colors are just a few of the numerous additives that are hidden beneath these well-known labels. These chemicals come from over 30 different countries. The extraction, processing, and delivery of each of these elements adds layers of energy use and carbon emissions. While we often associate climate change with agriculture and livestock, the impact of ultra-processed food on the environment is a growing concern. These commodities, which are staples of supermarket shelves and diets around the world, necessitate an intricate and energy-intensive supply chain that contributes to pollution, deforestation, and global warming.

What Makes Ultra-Processed Foods So Environmentally Harmful?

The impact of ultra-processed food on the environment starts at the source—its ingredients. Producing and processing these components involves multiple high-emission steps:

• Deforestation from raw materials: Sugar, cocoa, and palm oil production cause significant forest loss. Since 1850, agricultural growth has been the primary cause of about 90% of the world’s deforestation.
• Energy-intensive manufacturing: Processes such as packing, chemical modification, and refining require a significant amount of energy.
• Global transportation chains: Before ingredients from dozens of nations reach consumers, they are sent, processed, and then shipped again.
• Petroleum-based additives: Preservatives and artificial dyes are derived from fossil fuels, which increases emissions.

For example, petroleum and heavy metals like copper and chromium undergo chemical reactions to produce the blue dye found in M&Ms (E132 and E133). The trash and emissions produced by each of these processes are rarely taken into consideration in company sustainability reports.

How Big Is the Carbon Footprint of Popular UPFs?

Few food firms publish emissions data by product, despite many claiming to have “green” initiatives. Using estimates from outside sources provides insight into the scope of the problem.

According to data reviewed by the Sweden-based climate software company CarbonCloud, producing one kilogram of M&Ms results in the emission of nearly 13.2 kilograms of CO₂ equivalents. This amounts to 3.8 million tons of carbon dioxide, or around 0.1% of all US emissions, with over 664 million kg produced each year in the US.

Only a portion of the picture is shown by these figures. Because a large portion of the data, from manufacturing energy usage to fertilizer use, is either unreported or concealed behind corporate opacity, researchers refer to the food processing industry as a “carbon black box.”

The complexity of supply chains creates a great deal of unpredictability, as Professor Patrick Callery of the University of Vermont argues. Transport emissions are the easiest for businesses to disclose, but they don’t include the actual costs of chemicals or agriculture.

Why Is It So Difficult to Measure the True Environmental Cost?

One of the most significant challenges in assessing the impact of ultra-processed food on the environment is its complexity. Every ingredient has a complex production network that often spans several continents and involves hundreds of subcontractors.

Among the main obstacles are:

• Opaque supply chains: Food behemoths like PepsiCo and Mars don’t cultivate their own crops; instead, they rely on suppliers who often lack proper carbon accounting.
• Industrial secrecy: Chemical procedures that are proprietary and not publicly published include enzyme hydrolysis and hydrogen peroxide decolorization.
• Lack of standardization: Carbon reporting remains optional and varies by country.
• Greenwashing practices: The harsh reality of intensive industrial farming is often obscured by vague promises, such as “regenerative agriculture.”

Companies rarely address the systemic problem of large-scale agricultural monocultures that are fundamentally unsustainable, even when they make commitments to sustainability goals like Mars’ “Cocoa for Generations” strategy.

Can Consumers and Governments Drive Change?

Efforts are underway to assess the environmental impact of ultra-processed food using carbon accounting tools. Although people can choose more sustainably produced foods, experts concur that consumers shouldn’t bear the entire cost. Restructuring corporate and regulatory incentives is where the true power is.

Potential solutions include:

• Transparent carbon labeling: Require processed foods to disclose emissions to educate consumers.
• Environmental taxation: Charge businesses with carbon-based fees that are determined by the emissions of their products’ lifecycles.
• Support for regional food systems: Encourage the consumption of minimally processed, locally produced foods by raising public awareness and offering incentives to promote their adoption.
• Regulating marketing to children: Prohibit or limit the promotion of UPFs, especially those that are deficient in nutrients and rich in additives.

“The main point of ultra-processed foods is profit, not nutrition or sustainability,” contends Anthony Fardet, a senior researcher at France’s National Institute for Agriculture, Food, and the Environment. The entire industry should bear the hidden expenses.

Smaller, more transparent, and ecologically friendly food systems may replace corporate-controlled, international supply chains as a result of these reforms.

Why It Matters for the Planet — and for Us

A $2 packet of M&Ms has much more to cost than just the price at the register. Ultra-processed foods are a hidden contributor to environmental degradation, as they fuel intensive logistics, generate chemical waste, and lead to rainforest loss.

However, the issue is systemic. Sustainability objectives will remain secondary as long as industrial food production is driven by efficiency and profit. For this reason, rather than focusing only on reformulation or “healthier” product lines, experts are advocating for more profound structural change.

Fardet highlights that cutting a product’s sugar or salt content is only greenwashing. “The entire picture needs to be changed.”

Emissions can be significantly reduced by promoting more locally grown, whole foods, such as fruits, cereals, legumes, and minimally processed goods. However, long-term development will necessitate strong government policies, corporate responsibility, and cultural changes in our food perceptions.

Frequently Asked Questions (FAQs)

Q1. What foods fall under the category of ultra-processed foods (UPF)?

UPFs are commercial formulations that contain very little whole ingredient content and are primarily or exclusively composed of chemicals derived from foods and additives. Candy, chips, sodas, and fast food are a few examples.

Q2. Are UPFs made from plants more environmentally friendly?

Not always. Even if plant-based products help lower livestock emissions, substantial carbon footprints are still produced by the intensive industrial processing, shipping, and packaging that go into them.

Q3. How can customers minimize their environmental impact?

Choose minimally processed, locally grown foods; buy in bulk to reduce packaging; and support companies that hold third-party sustainability certifications and maintain transparent supply chains.
